HIV transmission - fingering, possible exchange of body fluids

Question: 

Hi there,

Recently I engaged in rimming and brief fingering from a man where I was on the receiving end. He did not know his status 100%, but otherwise I am aware that both of those activities are a negligible risk. However, I do know know that he was engaged in condom-less sexual activity with a man who is HIV undetectable within a few hours of me.

I am essentially concerned if he had not washed his hands after engaging in anal intercourse or being in contact with body fluids, how much of a risk I would be in? I will be getting a test within 11-12 weeks, but otherwise I find conflicting information on the internet in terms of how long HIV can survive outside the body. I understand viral loads can be in different levels, even when someone is undetectable.

Finally, I also engaged in protected sex (receiving) with another fellow. When he pulled out he, ejaculated on my buttock to my surprise, and some near/on the entrance to my anus. I wanted to also ask at what point do mucus membranes begin in the anus? I stood up quickly, but the combination of these two events has asking myself things I had not considered before! Thank you.

Answer: 

Hi there and thank you for reaching out to AIDS Vancouver with your questions! We're happy to help.

You're correct that the two activities you engaged in were Negligible Risk for HIV transmission.

The question you pose, about risk from potential bodily fluids on his hand, is a good one! The answer is that there is No Risk from those potential bodily fluids. The reason for this is that HIV is a delicate virus that cannot survive outside of the body. This means, upon exposure to the outside environment (such as on someone's hands, or any object) the virus becomes inactivated and damaged, and can no longer be transmitted. This eliminates any risk involved. That's why you need direct contact of bodily fluids for transmission to occur, and inanimate objects cannot transmit HIV.

Protected sex is considered a Low Risk activity meaning there have been a few cases of transmission in this way, but they're usually under certain identifiable conditions. An identifiable condition would be if the condom broke. If it didn't break, the risk if greatly diminished. Ejaculating on you is No Risk for the same reasons as said above. The virus cannot survive outside of the body, so it's no risk unless the ejaculation was inside of you. The outside of the anus does not pose a risk for transmission.

I hope this helped! For more information on HIV transmission, please visit avert.org.
